Abstract:
Test results on the pullout strength of reinforcing bars embedded in concrete are reported. The test specimens are 1.5, 3, and 6-in. cubes with geometrically similar bars. The results are found to be consistent with Bazant's size effect law for the nominal stress at softening failures due to distributed cracking. Based on the size effect law, an approximate formula predicting pullout strength is developed.
